PowerMatrix provides the MOST efficient and compact next-generation high-performance power supplies for emerging technologies, such as GPUs, xPUs, AI server, datacenters, drones, EV, aerospace, etc. Based on patented circuit topology, embedded packaging, and novel magnetics, our power supply systems can reduce energy loss by up to 50%. We have developed several prototypes and are collaborating with world-leading customers.

Our first product, Stillwind Search, makes finding an electronic part as easy as writing a text message. The search engine turns natural language queries into fine-grained specifications that are matched against our proprietary database of millions of parts. This is the first step towards autonomous electrical engineering.

E-waste recycling facilities spend most of their time and effort sifting through discarded electronics, searching for valuable devices, refurbishing them, and reselling them in second-hand markets. Our first product is an AI-enabled robotic system that integrates with these facilities to assess and refurbish hundreds of laptops a day without any human intervention. The system tests laptops, wipes their hard drives, photographs them, and posts them on online marketplaces for resale, regardless of model, manufacturer, or operating system.

Diode automates circuit board design. We work with hardware companies to get them the PCBs they need, fast.

atopile is a new language to design electronic circuit boards with code. We replace point and click graphical interfaces with code to bring software level automation and reuse to the field of hardware design. Our project is open source on GitHub! https://github.com/atopile/atopile

Tuesday makes delightful robots that tidy your home for you

Eze is your all-in-one hub for IT asset management, procurement, and recovery. Easily track every laptop, phone, and license from purchase to retirement with real-time visibility across your organization. Need new equipment? Order directly from vetted suppliers at competitive prices. Upgrading? We’ll handle buybacks, trade-ins, and recycling — so you recover value from your old tech instead of letting it collect dust. From automated asset tracking to one-click purchasing and vendor management, Eze keeps your inventory accurate, your costs low, and your team focused on work that matters — not spreadsheets. Whether you’re scaling fast or streamlining operations, we make sure your IT is always working for you.

Engineering tools should be as streamlined and smart as everything else in your life: as your phone, as your email, as all the apps that help you manage your day-to-day. Your work should be as efficient as possible so you can generate innovative ideas, design elegant technology, and manufacture at scale, all because you can focus on the right things. There should not be any distractions caused by poorly designed websites, unreliable data, or unwieldy spreadsheets of haphazard electronic component information. You should be able to compare components, find important technical information, and easily grasp the spectrum of parts that will be a match for your design. This is what Octopart strives for. Finding electronic component information should not be holding engineers back from bringing ideas to life quickly and efficiently. We believe that pricing, availability, technical specifications, and reference designs should be transparent, fast to find, and easy to understand. That’s why we create powerful, intelligent tools that streamline the engineering workflow and enable fast decision making. Octopart provides accurate and complete data for millions of electronic components in a way that makes it easy to find and compare parts. Focus on the important stuff: building the technology of the future.
